Paper Circuit PCBs?

Author Paper Circuit PCBs?

I just built a Grassic Organ on paper and it doesn't work, I figured it wouldn't because my free hand skills aren't great.

I love the sound of this circuit though thanks to smog filter on youtube for showcasing almost all of the paper circuits! (video below)

Anyway I would love to build multiple grassic organs and eventually the Rollz-5 (does anyone know if I can still get a meng qi board??) and Would be great to have actual PCBs to have a better shot at them working.

Has anyone made PCBs? Or knows where to purchase them? Maybe a limited run of them would be in order...

I messaged meng qi a while ago through etsy, he said he was working on a new rollz 5 pcb. I've seen one pop up on eBay for $100, which was $50 more than I wanted to spend.

I built several rolls, an ultrasound, and most of a gong. The rollz were very easy, but I found soldering to the chips on the other circs extremely annoying.

I too am interested in any paper circ pcbs.

I just Messaged Meng qi through etsy as well.

"Hi, Rollz-5 pcb is in production right now and Grassi is in stock. So both would appear in the shop soon!"

so sweet!! screaming goo yo screaming goo yo screaming goo yo

EDIT: on further inspection the grassi pcb is most likely the 'Old Mr. Grassi' paper circuit, not the grassic organ I was looking for...

Paper circuit PCBs go for sale on the 'Ciat Lonbarde Addicts' facebook group too. Gerassic organ, Esoterica Spikering, Old Mr Grassi etc

I was shocked for your design, I did not weld on paper or connected to the circuit.

This site has pcb manufacturers in all regions, but I have not used it.
After a friend recommended I used the wellpcb, is a pcb prototype and assembly of the manufacturers. I ordered a small batch of pcb board, the price in a reasonable range, the quality is fine, I weld by myself, did not use the assembly service.

I built a Lil Sidnrecently, using a PCB from Dennis (Bomono on Instagram m). Works likes a dream.

I've been having problems with building a lil sidrassi myself. I etched some PCBs using the paper circuits for a toner transfer but I used a different FET and op amp and i think thats my problem. I also used banana jacks instead of brass pegs. I get sound from some of the outputs but its not was I was expecting. Apprehensive about ordering the right parts from mouser because I ordered from them last week and they're still not here even though I only live an hour away....
